The Raspberry Pi Sky Miner - How to Mine On Your Raspberry Pi

Raspberry Pi Sky Miner is an excellent piece of software for the Raspberry Pi. I've been a big fan of the Raspberry Pi and its little computers since it was released over two years ago. As with most other Linux-based operating systems, you can get the full version of the software from the Raspberry Pi website or from a Linux distribution's website. This software will allow you to mine for yourself on the Raspberry Pi by using the Open-VGS Miner software.
Raspberry Pi miners are a bit different than regular computers because they use a special computer called a 'dedicated' computer. This dedicated computer is designed specifically for mining, and it can be configured in such a way that you will be able to configure your Raspberry Pi to work with a specific software program, such as the Raspberry Pi SkyMiner. You won't have to use a regular PC like you would for your standard tasks or software.
It will be important to understand how the Raspberry Pi works and how the Open-VGS Miner software works. For those who don't know much about the Raspberry Pi, it is a tiny, cheap, and powerful computer that is perfect for anyone who wants to learn more about the Linux operating system. The Raspberry Pi is an ARM-based single-board computer. The Raspberry Pi uses a Broadcom BCM2835 microprocessor.
The Raspberry Pi is very easy to program and is easy to use. If you've ever installed Linux on a computer, you know how simple it is to use Linux. You simply follow some simple instructions and the Linux program will do all of the work. The same thing happens when you are installing the Open-VGS Miner on the Raspberry Pi. Raspberry Pi miners have been created in order to perform advanced and complex mathematical calculations. This type of computing is only possible with the Raspberry Pi because it has a built-in processor called the Broadcom BCM2835. This chip is able to perform a large variety of operations quickly and with a high degree of accuracy.
The Open-VGS Miner will allow you to configure the Raspberry Pi to work with the OpenVGS Miner software, which allows you to easily set up a mining operation on your Raspberry Pi. You don't need to be an expert in computers to install the software on your Pi. You also don't need any technical knowledge to operate the software, so it's perfect for newbie Raspberry Pi users who want to try their hand at mining without too much difficulty. Once you've installed the software and configured the Raspberry Pie, you'll be ready to start mining. Just set up your Pi to use the OpenVGS Miner software, and you're ready to start mining.
The Raspberry Pi Sky Miner will automatically detect the best locations to mine at, depending on the information gathered from the Raspberry Pie's built-in GPS. When you start mining, you'll automatically send your current location to the software, and it will tell you where to mine next. Once you are done mining, you will be notified via email. You can configure the software to automatically send your mining location when you are online. The software also makes sure that your mining account is never accessed by anyone else.
The Raspberry Pi SkyMiner also has an integrated LED display. This display will show the status of your mining account and your mining activities. You can even see how many blocks you mine, and the average rate of your mining. The Raspberry Pi SkyMiner can even automatically shut down once you are done mining. It will also let you know if the current block count is over one hundred thousand. so you don't overheat your Raspberry Pi. Once you are done mining, you will be notified on your email, and then you can view your account balance, your earnings, and the number of blocks mined. in a nice graphical format. The software will also give you statistics such as how many blocks you mined in a certain time period, and how fast your computer was able to mine.

Step by Step guide for setting up the SkyCoin miner at the beginning level.

Below is that the commands to update your Skyminer (once in a time)

cd $GOPATH/src/github.com/skycoin/skywire
git reset --hard
git clean -f -d
git pull origin master
cd $GOPATH/src/github.com/skycoin/skywire/cmd
go install -v ./...

You have to edit your startmanager.sh and startsecond.sh files in nano.

This is the Skyminer raspberry pi 3 B+ skywire skyminer setup guide. Use at your own risk, do your own research.

Hardware needed for setting up the miner.

- Raspberry Pi 3 Model B+

- Pairs of Heatsinks

- 16GB Sandisk Class 10 A1 SD Cards

- 1ft ethernet cables

- Micro USB cables

- USB Power Supply- Anker 60w

- Ethernet Switch-TP-Link TL-SG1016D 16-Port Gigabit
- Router- Up to you, OpenWRT preferred


- SD Card Formatter to format cards, Win32 Disk Imager to flashcards, and Putty to attach to pi.

Step 1. Flashing SD cards with image file
1. First download the skywire image file, either from forum skywug.com
The file size is between around 700MB and can be during a .rar file. So you would like to extract it with WinRAR or 7zip.
2. Open SD Card Formatter and Win32 Disk Imager
3. Prepare SD cards during a miner that you simply can keep them organized so you recognize which of them are flashed etc.
4. Quick Format and there's no got to change any settings
5. Now format then write(not read) the IMG file using Win32 DI

WIN32 Disk Imager Raspberry PI 3
6. Flash all the cardboards (this can take 10-15mins per) take care after flashing windows may ask you to format the card so either eject or decline the format.

Step 2. Assembly
Depending on your DIY Skyminer setup assemble your raspberry pis either with acrylic stacking layers with standoffs or if you've got a custom 

case build. Get them secured and free from any metal which will cross-connections/short any of the boards. Also always handle with care just 

around the edges of the board. I assembled only enough in order that I could power up all the boards and configure them before assembling them into a frame.

Step 3. Configuration
If your flashing of the SD cards is correct once you power up the boards there should be a red then a touch green light on. Also you 

will have a light-weight on the ethernet ports. the subsequent thing to see is your remote access via SSH with Putty. First, you would like to seek out the IP addresses of the raspberry PIs.

A. Find DHCP Client list within your router via browser attend the address of your router (google your router if you're unsure the way to find it)

B. After finding your Client list hopefully you see all of your raspberry pis listed. I had to power down and on maybe a time or two before they all showed up. you would like to export or copy the IP addresses as we’ll need them to access via Putty within the next step. (*Record IP addresses for each raspberry as you go, but in later steps, we’ll change them to static IPs).

Step 3.1. Putty
A. After recording the IP addresses you would like to now login to everyone and configure them. Start with powering one at a time if you would like to number/order them for troubleshooting purposes. If you've got never used putty do a fast search and see how it works but you employ your IP address to access each raspberry pi.

B. After putty connects you'll be prompted to enter a username then the password. If your a beginner its best to try to do only one putty session at a time but you'll also run multiple sessions to hurry to process up.

Note: when typing password you'll not see any characters

Side note: Remember to stick you only right-click 

This is a short-lived password it'll change below (username stays the same)

username: pi
password: raspberry

Copy code lines one at a time:

sudo apt-get -y update
sudo apt-get -y upgrade

C. Now on to raspberry pi configuring:

sudo raspi-config

At now a raspberry configuration interface will crop up. you'll get to do two things:

Create a password (follow prompts, navigate with arrows, and enter key)
Change hostname- Network options>Hostname (IE mine each came up as raspberry pi so I just added variety to the top of each)
After that attend finish and reboot. Ignore the closing connection error.

Step 3.2 fixing Static IP Addresses
A. rather than using the IP address that was automatically assigned we'd like to vary all to a static ip within the instruction file editor 

nano with:

sudo nano /etc/dhcpcd.conf

Three things to do:

1. Remove the # before each line

2. Add your new static IP for every raspberry pi. Your new static IP is often what you would like to create a sequence like for instance, 

192.168.102 then on (some IPs may already be in use so you'll switch up the sequence just keep a record of those in excel or notepad as you configure all.

3. confirm your router IP is correct

Crtl/x + Y + Enter to save lots of and exit (Before you exit counter check your IPs again which all the # are removed like below)

network static Ip address change
B. For changes to require effect:

sudo reboot

C. Finished there now repeat these static IP steps for every raspberry pi board you configure. in any case, boards have their static IP assigned 

you can view them in your DHCP client list in your router to ascertain the new IP address change.

Note: If you took a record of the automated IP address you'll now access the board with the new static IP address, not the old one.

*Don’t move forward until all boards have new assigned static IP addresses and are showing in your DHCP client list*

Step 3.3 Configuring Node Monitor
Node monitor is accessed via browser to ascertain if your nodes are online. You view the node monitor via your “manager node” IP address. 

Your_manager_ip:8000/#/ to access node monitor (after completion of below steps)

A. Designate a manager node- Pick one that creates sense for you counting on your IP sequence. (IE pick the …1.101 because the manager node)

B. Access your manager node via Putty- With new static IP and password

sudo nano startsecond.sh

This will mention a nano editor

Change the follow code to:

nohup ./node -connect-manager -manager-address MANAGER_NODE_IP:5998 -manager-web MANAGER_NODE_IP:8000 > /dev/null 2>&1 & echo $! > node.pid

Crtl/x + Y + Enter to save lots of and exit

C. Configure SSH keys between nodes:


It will undergo each node's IP address asking you yes or no and to enter your password for every raspberry pi node. Follow prompts until finished.

D. Reboot and shut Putty session

E. Now you ought to be ready to proceed to “YOUR_MANAGER_IP:8000/#/”

default password:1234

F. you'll be prompted to vary your password and re-login.
